Abstract
In order to study the problems posed by lightning stroke on vastly exposed transmission lines, it is essential to study different lightning overvoltage phenomena. One of the most significant electrical transients caused by lightning is backflashover. In this paper, by applying Monte Carlo method and considering accurate models of transmission line, grounding system and physical model of breakdown in insulator gap, the backflashover is studied on a 230 kV double circuit transmission line. To apply the proposed approach, the selected case study is simulated in EMTP-RV software and the results are presented.
